For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] refer to Figure 1-4 An intelligent hot air circulation control system includes a base 1, the base 1 is provided with a ventilation groove 11, a withering trough body 2 is provided above the ventilation groove 11, and a plurality of ventilation holes are provided at the bottom of the withering trough body 2 to facilitate the entry of hot air from the bottom to achieve the withering of tea leaves in the withering trough body 2; a vibration device 3 is connected between the withering trough body 2 and the base 1, and the withering trough body 2 is vibrated regularly by the vibration device 3; thereby, the tea leaves in the withering trough body 2 follow the vibration, realize the stir-frying of the tea leaves, and improve the uniformity of the distribution of the tea leaves in the withering trough body 2.

[0023] A plurality of air guide units 12 are arranged in the ventilation groove 11, and the plurality of air guide units 12 are evenly arranged along the width direction of the base 1; hot air units 4 are connected to both sides of the ventilation groove 11, and hot air is transported into the ventilation groove 11 through the hot air units 4 to achieve withering of the tea leaves; a regulating device 5 is arranged between the air guide unit 12 and the withering trough body 2, and the regulating device 5 can evenly distribute the hot air transported to the ventilation groove 11 by the hot air unit 4 in the withering trough body 2.

[0024] In some embodiments, the air guide unit 12 includes two air guide plates 121, which are arranged to protrude from the symmetry axis of the ventilation slot 11 at an angle, and intersect to form a triangular air guide area 122, and the distance between the two air guide plates 121 gradually decreases in the direction away from the side wall of the ventilation slot 11 to guide and evenly disperse the hot air flowing through. The vertical distance between the air guide plate 121 and the side wall of the ventilation slot 11 is two-thirds to three-quarters of the length of the ventilation slot 11, so that the middle part of the ventilation slot 11 can have multiple air guide area 122 tips superimposed, thereby promoting the smooth flow of hot air and improving the uniformity of hot air distribution in the ventilation slot 11.

[0025] Specifically, when the hot air enters the ventilation slot 11, it will immediately encounter the triangular air guide area 122. Due to the triangular structure of the air guide area 122, the flow speed of the hot air in the air guide area 122 can be kept roughly equal, effectively avoiding the accumulation or loss of heat caused by uneven speed. At the same time, since the middle area of ​​the ventilation slot 11 is formed by the tip parts of the air guide areas 122 on both sides superimposed on each other, the flow speed difference between the hot air in the middle area and the hot air in the two side areas is reduced, thereby achieving uniform distribution of hot air in the entire ventilation slot 11.

[0026] In some embodiments, the regulating device 5 includes a partition block 51, a first regulating unit and a second regulating unit. The partition block 51 is coaxially arranged in the middle of the base 1. The first regulating unit is arranged on both sides of the base 1. The second regulating unit is arranged between the first regulating unit and the partition block 51. The first regulating unit and the second regulating unit form an isosceles trapezoidal first regulating area, so that after the hot air flows through the first regulating area, the hot air flow rate decreases. The second regulating unit and the second partition block form an inverted isosceles trapezoidal second regulating area, so that after the hot air flows through the second regulating area, the hot air flow rate increases, so that the hot air volume and wind speed in the withering trough body 2 located above the first regulating area and the second regulating area are consistent, thereby improving the uniformity of tea withering.

[0027] The first adjustment unit includes two first adjustment slits 52, a first fixing rod is provided between the two first adjustment slits 52, a first adjustment plate 53 is sleeved on the first fixing rod, the first adjustment plate 53 can rotate on the first fixing rod, and a first adjustment spring is connected between the first adjustment plate 53 and the side wall of the first adjustment slit 52. The second adjustment unit includes two second adjustment slits 54, a second fixing rod is provided between the two second adjustment slits 54, a second adjustment plate 55 is sleeved on the second fixing rod, the second adjustment plate 55 can rotate on the second fixing rod, and a second adjustment spring is connected between the second adjustment plate 55 and the side wall of the second adjustment slit 54. The hot air flow direction and distribution are controlled by automatically adjusting the positions of the first adjustment plate 53 and the second adjustment plate 55.

[0028] When the hot air is evenly diverted through multiple air guide areas 122 and flows upward, it first enters the first regulating area composed of the first regulating unit and the second regulating unit. The shape of this area is an isosceles trapezoid, where the hot air is regulated by the first regulating plate 53 and the second regulating plate 55. Depending on the flow rate of the hot air, the two regulating plates will automatically adjust their rotation angles until a balance is reached with the suction force generated when the hot air flows through. In this process, the hot air flow rate is effectively reduced, ensuring that the hot air has been preliminarily regulated before entering the withering tank 2.

[0029] Then, the hot air continues to flow through the second regulating area of ​​the inverted isosceles trapezoid formed by the second regulating unit and the partition block 51. Here, the flow rate of the hot air gradually increases due to the change in the shape of the channel, but thanks to the previous regulation, when it finally reaches the area above the withering tank 2, the air volume and wind speed of the hot air can be kept consistent, thereby achieving uniform heating during the withering process of the tea leaves.

[0030] In some embodiments, the cross-section of the partition block 51 may be an inverted isosceles trapezoid, and a plurality of through holes are evenly arranged on the partition block 51, so that the hot air at the bottom of the partition block 51 can flow into the withering trough 2 through the through holes, further improving the uniformity of the hot air distribution.

[0031] In some embodiments, the vibration device 3 includes at least two vibration motors 31, and the two vibration motors 31 are symmetrically arranged on one side wall of the withering trough 2. A plurality of vibration springs 32 are arranged around the bottom of the withering trough 2, and the vibration springs 32 are fixedly connected to the base 1. When the vibration motor 31 is started, a vibration force is generated and transmitted to the withering trough 2 through the vibration springs 32, causing it to vibrate regularly. This vibration causes the tea leaves to continuously roll and jump in the withering trough 2, increasing the contact area and frequency between the tea leaves and the hot air, thereby accelerating the evaporation process of the water inside the tea leaves and improving the withering efficiency.

[0032] In some embodiments, a vibration groove 13 is provided on the top of the ventilation groove 11, and a withering groove body 2 is inserted into the vibration groove 13. A plurality of vibration springs 32 are arranged on the bottom wall of the vibration groove 13, which can reduce the overflow of hot air and improve the utilization rate of hot air.

[0033] In some embodiments, the hot air unit 4 includes a fixing frame 41, and at least two hot air blowers 42 are arranged on the fixing frame 41. The blowing ports of the two hot air blowers 42 are connected to the ventilation slot 11. The hot air coverage area can be increased by multiple hot air blowers 42, thereby improving the circulation performance of the hot air in the ventilation slot 11. The ventilation slot 11 can cover the blowing ports of the hot air blowers 42, so that the hot air flowing out of the hot air blowers 42 can flow into the ventilation slot 11 to avoid the loss of hot air.

[0034] The specific working principle is as follows: The hot air unit 4 is started to deliver hot air into the ventilation groove 11. The hot air is guided by the air guide unit 12 to achieve preliminary uniform distribution in the ventilation groove 11. The hot air at the bottom of the first control zone flows to the withering trough body 2 through the first control zone, and the hot air at the bottom of the second control zone flows to the withering trough body 2 through the second control zone. The first adjustment plate 53 and the second adjustment plate 55 automatically adjust the angle according to the flow rate of the hot air to reduce the flow rate of the hot air. The second adjustment zone formed by the second adjustment unit and the partition block 51 gradually increases the flow rate of the hot air, so that the speed of the hot air at the two places in the withering trough body 2 is consistent, ensuring that the tea leaves are evenly heated.

[0035] At the same time, the vibration device 3 is started, causing the withering trough 2 to vibrate regularly, and the tea leaves roll and jump in the trough. Under the combined action of hot air and vibration, the tea leaves achieve a uniform and efficient withering process. At the same time, the first adjustment plate 53 and the second adjustment plate 55 rotate slightly under the action of the vibration device 3, thereby disturbing the hot air flowing through the first adjustment area and the second adjustment area, thereby increasing the change in the flow speed and direction of the hot air, and further improving the withering effect of the hot air on the tea leaves.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
